@thebluebus: for the record, we do plan to incorporate this kind of feature into the free version. We obviously have some other issues to sort out before we can get back to work on that kind of feature request.

I have WP 3.9.1 and NGG 2.0.61. I didn’t find the function nggCreateGallery in nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/nggfunctions.php . Could you please tell me how to modify the NGG search code to work again?

Here is what is currently working for me. I have WP 3.9 and NGG 2.0.61.
I reworked it a bit as version 2 plugin and created a file called in the plugins directory nggSearch2/nggSearch2.php with the following code.

Create a blank PHP file on your local machine called something like “nggSearch2.php” and paste this code into the file.

Using FTP and assuming that you are using the default WordPress plugins directory, create a directory called something like “nggSearch2” in the “/wp-content/plugins/” directory. Place the file, created previously, into the new directory.

Place this <?php if ( function_exists( 'ngg_images_results' ) ) ngg_images_results(); ?> in your themes “Search.php” file. It is WordPress best practice to make modifications to theme file by creating a child theme.

Log into the WordPress admin panel and activate the newly created plugin called “NextGen 2.0 Search engine”
